PACKING CONTAINER.

Application led June 9, 1924. Serial No. 719,014.

To all whom t mary concern.'

Be it known that I, ALFoNs MAUsnR, a citizen of' the Republic of Germany, and residing at 81 lvlarienburgstrasse, Cologne- Marienburg, Germany, have invented certain new and useful Packing Containers, of which the following is a specification.

In the well-known fluid-tight packing containers with welded-on bottoms or seats for the lids the connection of these latter parts to the rim of the container wall is made in such a manner that the said rim and the edge of the bottom or of the seat for the lid forms an end rib, which stands up more or less beyond the bottom or the seat for the lid. Then the packing containers are rolled, thrown, canted or lifted, stresses having a crushing or bending action occur in the rim of the container, which always result in a deformation of the rims, cause very considerable stressing of the Welded joint in its most unfavourable position at the edge of the container wall and bend round the container bottom and eventually cause it to tear or shear. Neither will this be prevented by reinforcing the edge of the container by means of rings of special cross-section laid around or embracing the same.

According to the invention stresses having a crushing or bending action are prevented from affecting the welded joints at the ends of the packing containers by the said joints heilig formed along a flat'curve and located in the plane of the container wall at such a distance from the edges of the container that the ends or the seat for the container lid themselves or reinforcing insertions laid in their edges form a support for the welded joints. The cross-section of the inserted supports is preferably such th at, even when the container' is rolled, thrown or canted, it can eXert n o lever action on the welded joint and cause the same to burst. This is effected by selecting a support of round or oval cross-section or, if the crosssection is cornered, by more or less rounding 'l he surface against which the welded joint rests. The welded joint may be further 0 protected externally and the ends of the Figs. G and 7 are cross sectional views of modified forms of the supporting member.

Referring now, more particularly to the drawing, ai designates the welded joint lying at the level of the container end o, c is the wall of the container, d the rim of the container end, j the supporting member in the rim of the container end and g the protective and reinforcing ring or hoop embracing the rim Aof the container end.

Vvfhat I claim is l. A container comprising a substantially cylindrical wall and dished ends, said ends comprising a substantially cylindrical fiange bent backoutwards so as to form a double flange, the outer part of said double flange forming a prolongation of the cylindrical wall of the container and the edge of the outer part of said flange being united to the edge of said cylindrical wall by an external welded seam, and an abutment arranged behind the welded seam to support said seam.

2. A container comprising a substantially cylindrical wall and dished ends, said ends comprising a substantially cylindrical flange bent back outwards to form a double flange, the outer part of said double flange forining a prolongation of the cylindrical wall of the container and the edge of the outer part of said flange being united to the edge of the cylindrical wall by an external welded seam, and an abutment located between the inner and outer parts of said double fiange, said abutment having a rounded surface in contact with the back of said seam to support said seam.

In testimony whereof I have signed my name to this specification.
